The discussion revolves around a problem in electromagnetic induction involving a metal rod moving through a magnetic field. The original poster seeks assistance in determining the potential difference induced across the rod as it moves in a uniform magnetic field.
The discussion is ongoing, with participants providing insights into the problem and questioning assumptions about the setup. Some guidance has been offered regarding the induced potential equation, but there is no clear consensus on the interpretation of the scenario.
Participants express confusion regarding the definition of a rod versus a loop and the implications of the rod's movement in a magnetic field. There is mention of a specific case where the magnetic field is parallel to the rod, which raises questions about the induced electromotive force (emf).
A rod is basically a thin cylinder, that is a cylinder with a length but no radius. This page may be useful for you... http://www.iop.org/Our_Activities/Schools_and_Colleges/Teaching_Resources/Teaching%20Advanced%20Physics/Fields/Electromagnetism/page_4817.htmlendeavor said:
I found out that the answer is 0... but since my conclusions are wrong, I don't know how this answer has been derived.Hootenanny said:Your equation is correct by the way but your conclusions are not
Ahh my apologies, your conclusion is correct I didn't see the 'parallel' bitendeavor said:I found out that the answer is 0... but since my conclusions are wrong, I don't know how this answer has been derived.
Oh Okay, thanks for the help anyway.Hootenanny said:Ahh my apologies, your conclusion is correct I didn't see the 'parallel' bit
